WELDER S HELMET Filed Dec. 26, 1928 2 Sheets-Sheet 2 Inventor A itorneyPatented Oct. 7, 1930 UNITED STATES PATENT OFFICE WILLIAM SHIRMER, OFPHOENIX, ARIZONA, ASSIGNOR OF ONE-HALF TO WILLIAM L. ALLISON, F PHOENIX,ARIZONA wntnnns HELMET Application filed December 26, 1928.

The" present invention relates to a helmet designed for use by. weldersand the prime object of the invention resides in the provision of ahelmet including a shield having transparent panels associated therewiththrough which the worker views his work, and means whereby the panel maybe raised and lowered by movement of the chin, thus leaving the Wearershands free for his duties.

A still further very important object of the invention resides in theprovision of a device of'this nature which is exceedingly simple in itsconstruction, inexpensive to manufacture, strong and durable, thoroughlyefficient and reliable in use and operation, easy to manipulate, light,and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as willappear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing: Figure 1 is a top plan View of the device embodying thefeatures of my invention,

Figure 2 is a vertical section therethrough, Figure 3 is a sideelevation thereof, and Figure 4 is a rear elevation thereof. Referringtov the drawing in detail it will be seen that the numeral 5 denotes ashield which is elongated vertically and curved diate their ends as at12 in the rear portion of the frame 6 at the ends thereof and links 14are pivotally connected therewith as at 15 and pivotally connected as at16 with ears 17 on the frame 7 A chin receiving member 18 is pivotallymounted in the lower portion of the shield as indicated at 19 and rods20 are connected with this chin receiv- Serial No. 328,597.

and the means preferred by me includes an.

arcuate bail 26, pivotally engaged at its opposite ends with an arcuateforehad band 22, as at 21. The band 22 is rigidly secured in spacedrelation to the upper portion of the shield 5 by a pair of Z-shapedbrackets 33. Adjacent the rear ends of band 22, an arcuate back headbail 23 is pivoted thereto as at 24.

A spring 25 is engaged in the center of the bail 23 for-engaging withthe back of the head to hold the supporting structure firmly on the headagainst accidental slipping off and, of course, to accommodate different sized heads.

If desired the bail 26 may be in the form of a strap adjustable by meansof a buckle 26 as indicated to advantage in Figure 4.

From the above detailed description it will be seen that when thisdevice is being worn by the welder he can view his work through thetransparent panel 10 in the usual well known manner but when it isdesired to raise this panel it is only necessary for him to open hismouth that is to move his chin downwardly thereby rocking the member 18causing the frame 7 with its panel 10 to move to the position shownclearly in Figure '3 Without the welder leaving his hands off anynecessary work, implement or the like. 1

If desired all parts of contact with the wearers face and skin may becovered with suitable padding not shown in the drawings. The principaladvantage claimed in this de vice is that it permits the wearer to useboth his hands in handling his tools and work and raising the glass ortransparent panel.

It is thought that the construction, operation, utility and advantagesof this invention will now be quite apparent to those skilled in thisart without a more detailed description thereof.

A catch 30 is pivotally mounted as at 31 on an ear 32 extendingoutwardly from one side of the frame 6 and when the frame 7 is raised toan open position this catch may be moved manually so as to be located inthe path of the frame 7 and hold it up for longer periods than would bedesirable than by the wearer holding his chin depressed.

The present embodiment of the invention, however, has been disclosed inconsiderable detail merely for the purposes of exemplification since inactual practice it attains the features of advantage enumerated asdesirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and inthe combination andarrangement of parts may be resorted to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages.

Having thus described my invention, What I claim as new is:

1. A device of the class described including a. shield, means forsupporting the shield in front of the face of a wearer, a frameprojecting forwardly from, the shield and an opening therein, a secondframe hingedly mounted on the first mentioned frame and having a paneltherein, and chin actuated means for swinging the second frame to anopen position, spring. means for normally holding the panel frameclosed, said chin actuated means comprising links pivotally engaged withthe second mentioned frame, leverspivotally engaged with the links androckably mounted on the first-mentioned frame, a. chin engaging memberpivotally mounted in the shield, rods connecting the chin engagingmember and the levers.

2. A device of the class described including a shield, means forsupporting the shield in front-of the face of a wearer, a frameprojecting forwardly from the shield andhaving an opening therein, asecond frame hingedly mounted on the first-mentioned frame and having apanel therein, a chin actuated means for swinging thesecond frame to anopen position, spring means for normally holding the panel frameclosed,said chin actuated means comprising links pivotally engaged with thesecond-mentioned frame, levers pivotally engaged with the links, androckably mounted on the first-mentioned frame, a chin engaging memberpivotally mounted in the shield, rods connecting the chin engagingmembers and the levers, the'means for supporting the shield comprising aforehead band rigidly secured to the shield, and a back bail pivotallysecured to the forehead band.

3. A device of the class described including a shield, means forsupporting the shield in front of the face of a wearer, a frameprojecting forwardly fromthe shield and having an opening therein, asecond frame hingedly mounted on the first-mentioned frame and having apanel therein, a chin actuated means for swinging the second frame to anopen position, spring means for normally holding the panel frame closed,said chin actuated means comprising links engaged with thesecondmentioned frame, levers pivotally engaged with the links, rockablymounted on the firstmentioned frame, a chin engaging member pivotallymounted in the shield, rods connecting the chin engaging members and thelevers, the means for sup-porting the shield comprising a forehead bandrigidly secured to the shield, a back bail pivotally secured to theforehead band, and a strap secured to the forehead band to extend overthe top of the head of the wearer.

4. A device-of the class described including a shield, means forsupporting the shield in front of the face of a wearer, a frame projecting forwardly from the shield and having an opening therein, a.second frame hingedly mounted on the first-mentioned frame and having apanel therein, a chin actuated means for swinging the second frame to anopen po-v sition, spring means for normally holding the panel frameclosed, said chin actuated means comprising links engaged with thesecondmentioned frame, levers pivotally engaged with'the links, androckably mounted on the first-mentioned frame, a chin engaging memberpivotally mounted in the shield, rods connecting the chin engagingmembers and the levers, the means for supporting the shield comprising aforehead band rigidly secured to the shield, a back bail pivotallysecured to the forehead band, a strap secured to the forehead band toextend over the top of the head of the wearer, and a spring of U-shapedformation secured .to the back bail.

In testimony whereof I afiix my signature.
